Cannot generate web service client from WSDL

See https://intellij-support.jetbrains.com/hc/en-us/community/posts/207997429-Web-service-client-generation-problem.

What engine do you use? Should work with Axis2.

If I select any other engine in the facet other than Axis I get the following error: Set valid {engine} path int he WebServices plugin settings....

I have no idea what path you are referring to.....

Which Axis2 version do you use in Web Services settings? What path is specified?

I am not using Axis2 I am using Axis. I still do not understand the pointing to some web service engine path. Is there a separate install for each web service engine? Is there a tutorial on how to setup the soap web service engines for IntelliJ?

There is no support for Axis, only Axis2, see https://www.jetbrains.com/help/idea/enabling-an-extra-ws-engine-web-service-client-module.html.

I was able to download and setup Axis2, I was able to generate a stub from IntelliJ but I cannot make reference to the stub.

It doesn't show as a standard java class also part of the problem is the shear size of the stub class (9.5 MB). 

The following properties may affect it:

#---------------------------------------------------------------------
# Maximum file size (kilobytes) IDE should provide code assistance for.
# The larger file is the slower its editor works and higher overall system memory requirements are
# if code assistance is enabled. Remove this property or set to very large number if you need
# code assistance for any files available regardless their size.
#---------------------------------------------------------------------
idea.max.intellisense.filesize=2500

#---------------------------------------------------------------------
# Maximum file size (kilobytes) IDE is able to open.
#---------------------------------------------------------------------
idea.max.content.load.filesize=20000

Try increasing the values so that your 9.5MB stub fits. Put the modified values in Help | Edit Custom Properties.
